Monorail Car´s Wireless Control System based on Smartphone Platform

To meet the mountainous districts situation in China, this paper introduces a monorail car´s wireless control system used in orchard which is based on smart phone and GPRS wireless communication technology. The system can obtain monorail car´s speed and position information by rotary encoder, control and transmit data by wireless communication. A SMS module on Windows Mobile Embedded OS 6.1 is developed based on GSM protocol system. Smart phone can receive car´s initial information and send orders to the on-vehicle controller for operating the car by GSM message. It describes how the hardware platform works and how to accomplish the design with software. Meanwhile, it tests the data transmission time and makes improvement. The rational design makes it easier to operate, which is proved to be available by tests.
